modem requires a simple analog “POTS” telco line for operation. It would be used as a first

Moving on in Figure TBD, the Local PIO closures are inputs provided to allow local
automation equipment to cue the iPump6420 to deliver specific operations at precise times.
These are fully balanced wire pairs, optically isolated from the i6420 chassis. Under Compel
network or local user control, specific programmed events (commands) may be associated with
any of the seven PIO inputs. When a closure is detected, that command is then immediately
executed, whether an order to play an audio file, or to switch the live satellite audio feed.
Two more functional blocks not yet discussed are used for unit Monitor and Control. This is
the Front-Panel system and the Serial M&C port. The Front-Panel features LEDs for indications,
a 2x20 character LCD for status and control menus, and a keypad interface for user control. The
Serial M&C port allows the user a local Terminal control session.
Lastly, the iPump6420 features an alarm relay contact closure, to allow use of the unit in
redundant fail-safe configurations. This closure indicates “Fail” when the unit is in an Alarm
state, or when AC power is removed.
